便攜式終端機是指，可在移動時同時進行通話及數據交換的通信機器。近來，便攜式終端機為了適應數字整合(digital convergence)時代，具有多種實用的功能。舉例而言，使用者可以透過操作便攜式終端機而使用AOD(audio on demand)和VOD(video on demand)服務、進行視頻通話或是下載遊戲等。便攜式終端機不再僅只侷限於通話功能。 A portable terminal is a communication device that can simultaneously perform a call and data exchange while moving. Recently, portable terminals have various practical functions in order to adapt to the digital convergence era. For example, a user can use an AOD (audio on demand) and a VOD (video on demand) service, perform a video call, or download a game by operating a portable terminal. The portable terminal is no longer limited to the call function.
前述這些實現於便攜式終端機上的性能越來越多，使用者愈 來愈需要更加便利快捷的操作這些性能，因此，便攜式終端機的製造公司向使用者提供一種具有觸控性能的顯示部(以下稱「觸控顯示構件」)。 The above-mentioned performances realized on the portable terminal are more and more, and the user is more and more Since it is necessary to operate these functions more conveniently and quickly, the manufacturing company of the mobile terminal provides the user with a display portion having a touch performance (hereinafter referred to as "touch display member").
依據使用在便攜式終端機上的觸控面板的種類差異，可區分為電容式、低阻膜式、表面超音波式、傳送式及紫外線式等等，當中，電容式觸控面板被廣泛地應用在便攜式終端設備上。 Depending on the type of touch panel used on a portable terminal, it can be classified into a capacitive type, a low resistance film type, a surface ultrasonic type, a transmission type, an ultraviolet type, etc. Among them, a capacitive touch panel is widely used. On a portable terminal device.
如第1圖所示，電容式觸控面板第1圖包括：由帶電體或PET絕緣體構成的框架(1)；在框架(1)的底面邊緣被鍍以後，遮蓋結合的銀電極(2)，並可印刷標記等的圖標部(3)；與框架(1)藉由雙面膠(4)結合的PC膜或玻璃(5)；在玻璃(5)的底面上藉由雙面膠(4)結合的PET材質帶電膜(6)；在帶電膜(6)的上部的偵測觸控部分的ITO鍍層，其係蒸鍍ITO等透明導電物質(7)；結合在ITO鍍層(7)的邊緣，用於向控制部傳送電子信號的銀電極(2)；在帶電膜(6)的底面上，用雙面膠(8)黏貼的LCD(9)。 As shown in Fig. 1, the capacitive touch panel 1 includes: a frame (1) composed of a charged body or a PET insulator; after the bottom edge of the frame (1) is plated, the combined silver electrode is covered (2) And can print the icon portion (3) of the mark or the like; the PC film or the glass (5) combined with the frame (1) by the double-sided tape (4); and the double-sided tape on the bottom surface of the glass (5) 4) Combined PET material charged film (6); ITO coating on the upper part of the charged film (6) for detecting the touch portion, which is vapor-deposited transparent conductive material such as ITO (7); combined with ITO coating (7) The edge is a silver electrode (2) for transmitting an electronic signal to the control unit; and an LCD (9) adhered to the bottom surface of the charged film (6) with a double-sided tape (8).
如前述之先前技術的電容式觸控面板，在合層工程中，要使用三個雙面膠(Optically Clear Adhesive，OCA tape；元件編號(4)及(8))，在製造觸控顯示構件中使用雙面膠的工序時，容易導致異物和氣泡的產生，增高產品不良率；此外，雙面膠的收縮及黏貼劑的不均勻，會導致更高的工程不合格率。 As in the prior art capacitive touch panel, in the layering process, three double-sided adhesives (Optically Clear Adhesive, OCA tape; component numbers (4) and (8)) are used to manufacture the touch display member. When the double-sided tape is used, the foreign matter and bubbles are easily generated, which increases the product defect rate. In addition, the shrinkage of the double-sided tape and the unevenness of the adhesive agent result in higher engineering failure rate.
又如第2圖所示，先前技術公開了一種電容式觸控面板的結構，其係使用框架材料，並以CNT材料鍍成，因而可提高顯示構件的強度，減少雙面膠的貼附工程，降低不合格率。 As shown in FIG. 2 , the prior art discloses a structure of a capacitive touch panel, which uses a frame material and is plated with a CNT material, thereby improving the strength of the display member and reducing the attachment of the double-sided tape. , reduce the rate of failure.
其中，觸控面板是由樹脂或框架等高強度材料構成，包括高 強度底板(18)、UV鍍層(22)、圖標部(20)、CNT鍍層(16)、銀電極(14)及接地極(24)、LCD(10)。 The touch panel is made of a high-strength material such as a resin or a frame, including a high Strength base plate (18), UV plating layer (22), icon portion (20), CNT plating layer (16), silver electrode (14), grounding electrode (24), LCD (10).
但是前述觸控面板的CNT鍍層(16)和銀電極(14)的印刷工序會導致產率降低，而高成本的強度底板(18)在前述的工序中發生不良時則會被分類為不良品，導致回收率很低。 However, the printing process of the CNT plating layer (16) and the silver electrode (14) of the touch panel may result in a decrease in yield, and the high-cost strength substrate (18) may be classified as defective when it is defective in the aforementioned process. , resulting in a very low recovery rate.
此外，形成觸控面板外觀的框架，是使用PC膜或鋼化玻璃的，為了考慮到便攜式終端機的美觀，需要使其四角圓滑，對此，係在框架的底面黏貼PET膜，但由於PET膜的硬度和復原力，雙面膠的黏貼力也會下降，出現黏貼分離等問題。 In addition, the frame forming the appearance of the touch panel is a PC film or a tempered glass. In order to take into consideration the aesthetics of the portable terminal device, it is necessary to make the four corners smooth. For this, the PET film is adhered to the bottom surface of the frame, but due to PET The hardness and restoring force of the film, the adhesive force of the double-sided tape also decreases, and problems such as adhesion separation occur.
本發明所欲解決之技術問題在於針對先前技術存在的上述缺失，本發明的目的在於：提供一種黏貼部材，其包含具有雙面黏貼性的黏貼層，黏貼層的一面上具有可印刷層，其可形成顯示文字、紋樣、圖形、金屬材質等的印刷層或蒸鍍層，且無須使用先前技術中所必需的PET膜，以此達成減少厚度、降低成本、提高生產率的黏貼部材。 The technical problem to be solved by the present invention is to provide the above-mentioned defects in the prior art, and an object of the present invention is to provide an adhesive member comprising an adhesive layer having double-sided adhesiveness, and a printable layer on one side of the adhesive layer. It is possible to form a printed layer or a vapor-deposited layer that displays characters, patterns, patterns, metal materials, and the like, and it is not necessary to use a PET film which is required in the prior art, thereby achieving an adhesive member having reduced thickness, reduced cost, and improved productivity.
本發明的又一目的在於：提供一種具有黏貼部材的觸控螢幕用顯示構件，尤指在可印刷層上形成印刷層、蒸鍍層的狀態下，貼附在框架上，在框架破損時，可防止框架破片飛散的具有黏貼部材的觸控螢幕用顯示構件。 Still another object of the present invention is to provide a display member for a touch screen having an adhesive member, which is attached to a frame in a state where a printed layer or a vapor-deposited layer is formed on a printable layer, and when the frame is broken, A display member for a touch screen having an adhesive member that prevents the frame from being scattered.

本發明之創作概念之一係為一種黏貼部材，其包括具有兩面黏貼性能的黏貼層及在黏貼層的兩面所具備的保護膜，黏貼部材具備可印刷層，形成於前述二保護膜之其中之一去除後所顯露出的黏貼層之一面，可印刷層可形成顯示文字、紋樣、圖形、金屬質感中任意一個以上的印刷層或蒸鍍層。 One of the creative concepts of the present invention is an adhesive member comprising an adhesive layer having adhesive properties on both sides and a protective film on both sides of the adhesive layer, the adhesive member having a printable layer formed on the two protective films One of the adhesive layers exposed after removal, the printable layer can form a printed layer or a vapor deposited layer that displays any one or more of characters, patterns, patterns, and metallic textures.
可印刷層是UV鍍層。 The printable layer is a UV coating.
依據本發明一實施例，係為具有黏貼部材的觸控螢幕用顯示構件，其包括：黏貼層，兩面具有黏貼性能；保護層，位於黏貼層的兩面中的任意一面上；可印刷層，位於黏貼層的另一面上，可形成顯示文字、紋樣、圖形、金屬質感中任意一個以上的印刷層或蒸鍍層；以及印刷保護層，用於保護印刷層。 According to an embodiment of the present invention, a display member for a touch screen having an adhesive member includes: an adhesive layer having adhesive properties on both sides; a protective layer on either side of the adhesive layer; and a printable layer located at On the other surface of the adhesive layer, a printed layer or a vapor-deposited layer that displays any one or more of characters, patterns, patterns, and metallic textures; and a printed protective layer for protecting the printed layer can be formed.
依據本發明的另一實施例，係為具有黏貼部材的觸控螢幕用顯示構件，其包括：一黏貼部材，包括：黏貼層，兩面具有黏貼性能；保護膜，位於黏貼層的兩面中的任意一面上；可印刷層，位於黏貼層的另一面上，可形成顯示文字、紋樣、圖形、金屬質感中任意一個以上的印刷層或蒸鍍層；一蒸鍍層，形成於可印刷層上並可散亂外部光；一印刷層，形成於蒸鍍層上；以及一印刷保護層，用於保護印刷層。 According to another embodiment of the present invention, there is provided a display member for a touch screen having an adhesive member, comprising: an adhesive member comprising: an adhesive layer having adhesive properties on both sides; and a protective film located on both sides of the adhesive layer a printable layer on the other side of the adhesive layer, which can form any one or more printed or vaporized layers of characters, patterns, patterns, and metallic textures; an evaporated layer formed on the printable layer and can be dispersed Scattering external light; a printed layer formed on the evaporated layer; and a printed protective layer for protecting the printed layer.
在可印刷層的一側，具有有圖案的圖案部。 On one side of the printable layer, there is a patterned pattern portion.

印刷層係包括複數個層。 The printed layer includes a plurality of layers.
本發明的具有兩面黏貼性的黏貼部材的一面上係具有可印 刷層，其可形成顯示文字、紋樣、圖形、金屬材質等的印刷層或蒸鍍層，且無須先前技術中所必需的PET膜。 The side of the adhesive member having the double-sided adhesiveness of the present invention has a printable side A brush layer which can form a printed layer or a vapor-deposited layer for displaying characters, patterns, patterns, metal materials, etc., without the PET film necessary in the prior art.
因此，由於PET膜的厚度減少，不需要使用昂貴的進口PET膜，因而可以降低成本。此外，含有PET膜的結構在出現異物時，就不能再次使用；但是對於本發明而言，因為不需要使用PET膜，因而可以降低不良率，提高產率，即使在貼附於框架後出現不良時，也可以再次使用框架。 Therefore, since the thickness of the PET film is reduced, it is not necessary to use an expensive imported PET film, so that the cost can be reduced. Further, the structure containing the PET film cannot be used again in the presence of foreign matter; but for the present invention, since the PET film is not required, the defect rate can be lowered, the yield can be improved, and the defect occurs even after being attached to the frame. You can also use the framework again.
在可印刷層上形成印刷層、蒸鍍層的狀態下，將黏貼部材貼附在框架上，可以避免框架破損時破片飛散。 In the state in which the printed layer and the vapor-deposited layer are formed on the printable layer, the adhesive member is attached to the frame to prevent the fragments from scattering when the frame is broken.
不需要厚的高強度PET膜，黏貼部材可直接黏貼於框架，即使框架具有具有彎曲結構，也可以直接黏貼。 No thick high-strength PET film is required, and the adhesive part can be directly adhered to the frame, and even if the frame has a curved structure, it can be directly adhered.

本發明中所記載的實施例及圖示僅為本發明之一較佳實施例而已，當不能以之限定本發明實施之範圍；即大凡依本發明申請專利範圍所作之均等變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。 The embodiments and the illustrations of the present invention are only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto; It should remain within the scope of this invention.
首先，如第4圖所示，黏貼部材120的兩面都具有黏貼性，且厚度很薄。作為一實施例，可使用OCA(Optically Clear Adhesive)膠帶，也可使用擁有兩面具有黏貼性、透明且厚度薄知特點的各種膠帶。 First, as shown in Fig. 4, the adhesive member 120 has adhesiveness on both sides and is thin. As an embodiment, an OCA (Optically Clear Adhesive) tape may be used, or various tapes having adhesiveness on both sides, transparency, and thin thickness may be used.
以下對黏貼部材120進行詳細說明，黏貼部材120包括：兩面都具有黏貼性能的黏貼層122以及用於保護黏貼層122兩面的保護膜124。 The adhesive member 120 will be described in detail below. The adhesive member 120 includes an adhesive layer 122 having adhesive properties on both sides and a protective film 124 for protecting both sides of the adhesive layer 122.
其中，在黏貼部材120上還具有可印刷層126。 There is also a printable layer 126 on the adhesive member 120.
可印刷層126可在已去除保護膜124且具有黏貼性能的黏貼層122上印刷或蒸鍍。 The printable layer 126 can be printed or evaporated on the adhesive layer 122 from which the protective film 124 has been removed and has adhesive properties.
也就是說，可印刷層126可形成文字、紋樣、圖案、金屬質感等的印刷層130或蒸鍍層140。 That is, the printable layer 126 can form the printed layer 130 or the vapor deposited layer 140 of characters, patterns, patterns, metallic textures, and the like.
其中，黏貼層122在去除保護膜124時，具有黏貼性能，不能印刷。因此，當黏貼層122上具有的一對保護膜124中的任意一個被去除時，所露出的面上形成可印刷層126，也可形成印刷層130或蒸鍍層140。 Among them, the adhesive layer 122 has adhesive properties when the protective film 124 is removed, and cannot be printed. Therefore, when any one of the pair of protective films 124 provided on the adhesive layer 122 is removed, the printable layer 126 is formed on the exposed surface, and the printed layer 130 or the vapor deposited layer 140 may be formed.
在本發明的實施例中，可印刷層126可選擇使用UV鍍層，其具有高透明度、厚度薄及一定的強度。 In an embodiment of the invention, the printable layer 126 may optionally employ a UV coating having high transparency, thin thickness, and a certain strength.
在黏貼層122的兩面當中不形成可印刷層126的那面，還剩下保護膜124；當保護膜124去除後可與框架110黏貼。 On the side of the both sides of the adhesive layer 122 where the printable layer 126 is not formed, the protective film 124 remains; when the protective film 124 is removed, it can be adhered to the frame 110.
接下來，以第5圖對黏貼部材120的多種實施例進行詳細說明。 Next, various embodiments of the adhesive member 120 will be described in detail with reference to FIG.
第5圖是使用本發明觸控螢幕用顯示構件的面板的外觀俯視圖。 Fig. 5 is a plan view showing the appearance of a panel using the display member for a touch panel of the present invention.
如圖所示，觸控螢幕用顯示構件100係設置於構成採用電容式觸控螢幕之框架110的後側，觸控螢幕用顯示構件100包括框架110。 As shown in the figure, the touch screen display member 100 is disposed on the rear side of the frame 110 constituting the capacitive touch screen, and the touch screen display member 100 includes the frame 110.
框架110採用一般的鋼化玻璃，黏貼部材120係黏貼於框架110的後方，在框架110破損時，可防止玻璃飛散。 The frame 110 is made of general tempered glass, and the adhesive member 120 is adhered to the rear of the frame 110, and when the frame 110 is broken, the glass is prevented from scattering.
其中，在框架110的後面係黏貼上已去除保護膜124(如第4圖，位於下面的保護膜124已去除)的黏貼層122。 The adhesive layer 122 on which the protective film 124 has been removed (as shown in FIG. 4, the underlying protective film 124 has been removed) is adhered to the rear of the frame 110.
黏貼層122的後方形成可印刷層126，也可形成印刷層 130或蒸鍍層140。 A printable layer 126 is formed behind the adhesive layer 122, and a printed layer can also be formed. 130 or evaporated layer 140.
在黏貼層122的後方採用印刷層130或蒸鍍層140時，其不同的細部結構如下所述。 When the printed layer 130 or the vapor-deposited layer 140 is used behind the adhesive layer 122, the different detailed structure is as follows.
在觸控螢幕用顯示面板100的中央部具有透明的顯示窗152。 A transparent display window 152 is provided at a central portion of the touch panel display panel 100.
顯示窗152於可印刷層126的後方，不形成前述的印刷層130或蒸鍍層140，並在顯示窗152可透視的區域維持高透明度。 The display window 152 is behind the printable layer 126, does not form the aforementioned printed layer 130 or vapor deposited layer 140, and maintains high transparency in areas where the display window 152 can be seen through.
在不具有前述顯示窗152的區域上，形成蒸鍍層140和印刷層130。 On the region where the display window 152 is not provided, the vapor deposition layer 140 and the printing layer 130 are formed.
印刷層130如第5圖所示，可透過框架110透視有顏色的文字或圖案，因為框架110、黏貼層122及可印刷層126為透明，具有顏色的印刷層130可向框架110外部透視。 As shown in FIG. 5, the printed layer 130 can see through the frame 110 a colored text or pattern. Since the frame 110, the adhesive layer 122, and the printable layer 126 are transparent, the printed layer 130 having a color can be seen through the outside of the frame 110.
蒸鍍層140在蒸鍍於可印刷層126的後面，其可用於散亂光並呈現金屬質感。在可印刷層126上具有圖案部128時，圖案部128被遮蔽可防止圖案部128產生散光情形，從而可以表現出金屬質感。 The vapor deposited layer 140 is vapor deposited behind the printable layer 126, which can be used to scatter light and present a metallic texture. When the pattern portion 128 is provided on the printable layer 126, the pattern portion 128 is shielded to prevent the pattern portion 128 from generating astigmatism, so that a metallic texture can be exhibited.
接下來結合第6圖對觸控螢幕用顯示構件100的細部結構進行詳細說明。 Next, the detailed structure of the touch panel display member 100 will be described in detail with reference to FIG.
